" Be it known that'WB,.RICHARD'GRIESER, a

citizen of the United States, residing at New York, in the county of NewYork and State of New York, aIId FREDERICK YATES, a

jt1on. Fig. 2 1s a plan .viewpartlyin section.

citizen-of the Dominion of Canada, residin at New York,-in the couiityof New York an -"S tate .of .New York, have invented certain new and useful Inprovenc ents in Oiling De: vices, hf which the following is a specification.

' This invention relates to lubricating de-.

vices for machinery that is moved from place.

to place and which will assume difi'erentpo;

U sitions relative to the leveipr horizontal line.

i Z O The object of the invention is to provide means in a casing contalning-a serles of bear-' mgn: embers such, for instance, as the crankcase ofan engine,whereby upon the crank-.

case being inclined from, thelevelposition the surplus lubricating-oiljwill be withdrawn from the lower end of the'crank-case and returned tothe upperend or. else forced di-l rectlylupon the bearing members. Our "in when the vehicle is on a ing members.

. vention is particularly applicable to motorvehicles in which the crank-case is inclined I This will causeasurplus of oil at the owermost end f the crank-case, which will result in too much oil being engaged by the bearings at thatend, tending to flood the cylinders and foul the spark plugs, inducing premature explosions and other troubles. Furthermore, the other end of the crank-case will-be without the lubricating-oil and the bearings will beconce heated and cut. By the present invention the oil is automatically withdrawn from whichever end of the crank-case is lowermost and is distributed uniformly throughout the crank-case and the oil is autom atically,

codled, dispensing with the need of watercooling.

A further object of the invention is to prolubricating-oil from opposite ends of the crank-casing when the casing is in the normal level position'and force the oil onto the bear- Thereby upon the crankcasing being inclined in either, direction the oil will be withdrawn from the lowermost end and forced upon the bearings,fwhile the upper end of the casing being dry no oil will be forced upon the bearin s. I

A further object of the inventionis to provide an in proved 1r. cans for lubricating thebearings .of a connecting-rod and crank and also of oiling the cvlmder or other recipro- ,ing-rods. V through the connecting-rod. Fig. 5 is a cating member with which the connectingrod is pivotally j-ointed. I

In the accompanying drawings, representing'one embodiment of our invention, Fig- 60 ure' 1 is afront elevation partly shown in see- Fig. 3 is an elevationof one of the connect- Eig. is a longitudinal section transverse'section of the connecting-rod on line 5 5, indicated in Fig. 4.; and Fig. 6 is a transversesection on the. line 6 6, indicated inFig i.

In Fig. 1 is represented a four-cylinder gasengine of the upright or vertical type, hav- 'ing four cylinders A, B, C, and D, in which operate trunk-pistons, The pistons a, and b" are shown in'section and the "adjacent part of the casing E. The istons a and I) operate 7 5 in the cylinders A an B and are connected with the crank K by connecting-rods 2 and 3, respectively, the connecting-rt) sbeing pivotally jointed to the trunk-pistons at their npper ends and are rovidedwithj onrnal-boxes 8o 4 and 5 at their ower ends, in which operate the crank-pins 6 and 7. The sameconstruction is followed withthecylinders G and D, but which are not shown. :At'one end of the crank-case E is an outlet 8, from which leads 8 5. a pipe 9. At the opposite 'end of the casing is an outlet 10, from which leads a pipe 11," both pipes extending toward the middle part of the casing and inclined downward,

and leading to a -T 12. qFroIn this T suitable piping 13 leadsupward and is connected with a reservoir 14; but a suitable fluid-actuator 15 is placed along this pipe for drawing the. oil'from the cylinder and forcing it into the reservoirf -'In the form shown a gear 5 force-pump (represented by 15) is used and actuated'from the main shaft 5- of the engine by chain- 17'. The pipe 13 leads into the reservoir 14 at 16 adjacent its top. The oil in the tank 14 passes out through a pipe 18, ICO whose open end. 19 leadsnearly to the bottom of the tank, thus formingasiphon. The pipe 18 conducts the oil back into the crank-casing and is provided with means for distributing the. 0i r0 5 so that it is uniformly supplie throughoutthe casing and eachend will re-' ceivef the proper amount for the bearings Itherein. a

r When the-engine is placed fore and aft on a grade,

motor-vehicle and the latter is ona either ascending or descending, obviously .one' end of the casing wilLbe elevated considerably above the other. The lower end will have the oil inthe casing crowded to that end, while'the other and up ermost end will be high and dry. Where t e splash system of lubrication is used, one or two cylinders and crank-bearings at that end will receive no lubrication, because i there is no oil to be splashed thereby. Hence the bearings. will becomedry and heated and will then tend to burn and cut, and any smallamount .of oil they may receive will become immediately carbonized. The spark lugs will also become foul very-shortly; b ent invention the oil that is nowat the lower end will run through the outlet 8 or. 10 and pass into the ipe 13. By means of thefluidactuator t 's 011 will be drawn u into the tank 14. From thence the oil will e forced out of the tank throu h the si hon-pipe and through the pi e 18 to e distri uted throughout the lengt of. the crank-casing. In the glrlesent inventionthe oil from the pipe 18 is ected upon each of the connecting-rods. This pi e I8 is provided with "branches 20, 21, 22, an 23, that lead into the casing at each cylinder, respectively, as indicated in section in Fig. 2. These pipes are provided with nozzles 24, whose position is at the extreme 'lower'portion of the cylinder, whereby the oil will be constantly received upon-some part of the connecting-rods By this*m'eans whichever end of the cylinder is depressed the oil flowing to. that end'will be forced, up by the pump into the reservoir-and thence be uniformly distributed to feed each of the pistons and bearings operatively connected therewith. When the casing is. level, the oil will be drawn from both ends; but should either end be elevated the oil running to the other end will be withdrawn and fed upon all of the connecting-rods.

The oil striking the connecting-rods will meet a surface whose inclination varies. When theconnecting-rod is in itsextr'eme Iu per and lower limits, it will be vertical and t e oil will meet a substantially perpendicular surface, but between these positions the connecting-rod is alternately inclined in opposite directions. When the connecting-red is inclined away from'the nozzle and toward the iston, the oil will naturally flow up and tend to lubricate the wrist-pin and cylinder, and when the connecting-rodis inclined in the opposite direction the oil will flow down the connecting-rod to lubricate the crankbearings, &c.

' In order to facilitate'the'movement of the oil alon the connecting-rods, each rod-is preferaby channeled, as shown,- tendin to cause the oil to flow along therod rather t an 'to,move"t0wards the sldes. At the lower.

part of the connecting-rod the channel terminates in an annular pocket 26', and one or more openings 2 7- are provided, leading from this pocket to the crank-bearmg By ut with the presthis means the oil flowing down the. channel will. be caught in the pocket, and hence be caused to flow directly u on the crank-bean ing. Some of the oil wi 1 pass around the pocket to the opposite side of the connectingrod and will be thrown off against the rear side of the cylinder. A assage 28 through the connectingrod from t e channel 25 to the opposite side-permits-some of the oil received on the rod to pass through and run down into the pocket on that side.

- By this means 'it is unnecessary to have sufiicient de th'of oil in the crank-case tofinsure splash ubrication, as the oil falling from the bearings will be constantly drawn out by the force-pump throughnir-cooled pipes into the air-cooled reservoir and from it fed directly upon the connecting-rods, and the .cooled oil caused to lubricate the cylinders,

crankbearings, and the Wrist pins; By means of the siphontub 19 a certain amount of oil will always be retained in the reservoir, and as soon as the en he. is started and the force-pump. operates oil will be directly fed upon the bearings.
